The UFC’s summer shuffle continues as the promotion has revealed that a light heavyweight clash between The Ultimate Fighter Brazil 3 coaches Chael Sonnen and Wanderlei Silva will now take place at UFC 175 on July 5 in Las Vegas. The current season of the reality show can be watched each week on the promotion’s digital network, UFC Fight Pass.

UFC 175 takes place from the Mandalay Bay Events Center and will be headlined by a middleweight title fight between champion Chris Weidman and former light heavyweight kingpin Lyoto Machida. The Sonnen-Silva match-up will serve as the co-main event.

As a result of the shift, a heavyweight bout between former UFC champion Junior dos Santos and Stipe Miocic will move from May’s UFC 173 event in Las Vegas to the headlining slot of UFC Fight Night 42 in São Paulo, Brazil. UFC Fight Night 42 takes place from the Ibirapuera Gymnasium.

Now, UFC 173 is without a co-main event, but UFC President Dana White declared that he was “not done working on that card.” UFC 173 takes place Saturday, May 24 from the MGM Grand Garden Arena in Las Vegas. The night’s main card will air live on pay-per-view. UFC bantamweight champion Renan Barao will put his 135-pound strap on the line against T.J. Dillashaw in the main event, while recent welterweight title challenger Robbie Lawler will square off with Jake Ellenberger.
